function setup() {
  let currentState = [];
  let i;
  let j;
  
  //code that populates the array
  currentState[0] = [undefined,undefined,undefined,undefined,undefined,undefined,2,4];
  currentState[1] = [undefined,undefined,0,1,3,3,5,5];
  currentState[2] = [undefined,undefined,0,1,2,2,4,4];
  currentState[3] = [undefined,0,1,1,2,3,4,5];
  i = 0;
  j = 1;
  
  //check the state of the array and iterators, for bugtesting
  console.log("i = " + i);
  console.log("j = " + j);
  console.table(currentState);
  console.log();

  //code that randomize each row, the result:
  currentState[0] = [undefined,4,undefined,undefined,undefined,undefined,undefined,2];
  currentState[1] = [3,3,5,5,undefined,undefined,0,1];
  currentState[2] = [2,2,4,4,undefined,undefined,0,1];
  currentState[3] = [1,2,3,4,5,undefined,0,1];
  i = 2;
  j = 2;
  
  //check the state of the array and iterators, for bugtesting
  console.log("i = " + i);
  console.log("j = " + j);
  console.table(currentState);
}

我在控制台中写console.table(currentState);的两个地方都得到了相同的状态。我想看看数组在随机化之前和之后的状态。现在两个console.table（）调用都显示了随机化之后的数组。这让bug测试变得很混乱。
我做错了吗？还是有别的办法？
